[0036] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] refer to Figures 1 to 4 The present invention provides an aerosol generating device 1, which comprises a housing 11, wherein the housing 11 has a first inner cavity 11a; a mouthpiece 10, wherein the mouthpiece 10 has a second inner cavity 10a and a suction port 13, wherein the mouthpiece 10 is movably disposed at one end of the first inner cavity 11a, and the extension direction of the mouthpiece 10 is ( Figure 1 and Figure 2 The other end of the first inner cavity 11a (shown in the X direction) is used to connect with the cigarette rod, the first inner cavity 11a and the second inner cavity 10a are connected, and at least form an aerosol channel; the atomization part 30 is arranged in the first inner cavity 11a, the atomization part 30 has an atomization cavity 31, and a heating element 32 is arranged in the atomization cavity 31. The heating element 32 heats the smoke liquid to generate aerosol that flows from the aerosol channel to the inhalation port 13 for the user to inhale; the first opening 21 is arranged on the housing 11 or the cigarette holder 10. Preferably, the first opening 21 is arranged on the cigarette holder 10.

[0038] Among them, reference Figure 1 and Figure 3 and Figure 4 , the cigarette holder 10 and the housing 11 can generate relative movement to open the first opening 21, the first opening 21 is connected to the outside, no smoke liquid flows into the atomization chamber 31, when the user inhales through the product inhalation port 13, the outside air can flow into the aerosol channel through the first opening 21 and then flow out of the product inhalation port 13, forming a first airflow path ( Figure 3 and Figure 4 As shown in C in the figure, the air pressure sensor will not be triggered, thus avoiding starting the heating element 32 and causing dry burning.

[0039] In addition, reference Figure 2 and Figure 5 and Figure 6 , the cigarette holder 10 and the housing 11 can generate relative movement to close the first opening 21, the first opening 21 is not connected to the outside, the smoke liquid flows into the atomization chamber 31, and when the user inhales through the inhalation port 13, the outside air can flow into the aerosol channel through the atomization chamber 31 and then flow out of the inhalation port 13, forming a second airflow path ( Figure 5 and Figure 6 D in the figure), and triggers the air pressure sensor, thereby triggering the circuit to be connected, and the heating element 32 heats the smoke liquid to generate aerosol for the user to inhale. The outside air will not flow into the aerosol channel through the first opening 21.

[0040] Thus, the aerosol generating device 1 of the present invention can prevent the heating element 32 from being triggered by mistake. When not in use, the aerosol generating device 1 forms a first airflow path. Even if inhalation is performed through the product inhalation port 13, the heating element 32 will not work, and at the same time, the smoke liquid will not flow into the atomization chamber 31, thereby preventing leakage. When it is needed to be used, the aerosol generating device 1 forms a second airflow path. Inhalation is performed through the product inhalation port 13, and the smoke liquid flows into the atomization chamber 31. The heating element 32 works to generate aerosol for the user to inhale through the product inhalation port 13, thereby improving the user's inhalation experience.

[0041] In other words, when not in use, the liquid outlet 24 of the liquid storage part 20 is closed. The first opening 21 is in an open state. At this time, when the aerosol generating system is used, the smoke liquid does not flow out. When the smoke is inhaled from the product inhalation port 13, the outside air flows from the first opening 21 to the product inhalation port 13. The pressure is not transmitted to the air pressure sensor, and the air pressure sensor is shielded to avoid starting the heating element 32 and causing dry burning. When in use, the control mouthpiece 10 and the shell 11 produce relative movement, the liquid outlet 24 of the liquid storage part 20 is opened, and the smoke liquid can flow out to the heating element 32 or the oil guide buffer body in the atomization part 30. At the same time, the first opening 21 is shielded by displacement and is in a closed state, and air cannot be taken in from the outside. The air pressure needs to flow from the bottom to the atomization part 30 so that the pressure sensor can sense the air pressure, that is, the air pressure sensor can sense the suction pressure and trigger the circuit to be connected. The air circulation trajectories of the first airflow path and the second airflow path are different, and the effects on the air pressure sensor are also different.

[0042] Preferably, the aerosol generating device 1 of the present invention has a first state and a second state. Figure 1 , Figure 3 and Figure 4In the first state, the first opening 21 is in an open state, the first opening 21 is connected to the outside, the atomization unit 30 stops working, and no smoke liquid flows into the atomization chamber 31. Figure 2 , Figure 5 and Figure 6 In the second state, the first opening 21 is in a closed state, the first opening 21 is isolated from the outside, the atomization unit 30 is working, and smoke liquid flows into the atomization chamber 31 .

[0043] Preferably, the mouthpiece 10 can be moved along the direction ( Figure 1 A) or away from ( Figure 2 The housing 11 is in a direction shown in the B direction) and generates relative movement with the housing 11 to open or close the first opening 21, wherein the distance ( Figure 4 The distance between the heating element 32 and the atomizing chamber 31 is not less than 0.5 mm. This is helpful to prevent the heating element 32 in the atomizing chamber 31 from burning dry. Preferably, when the cigarette holder 10 and the housing 11 move to abut each other, smoke liquid flows into the atomizing chamber 31.

[0044] In this embodiment, the cigarette holder 10 can be moved in a direction toward the housing 11 ( Figure 1 Alternatively, the cigarette holder 10 can move in a direction away from the housing 11 (as shown in the direction A in the figure) to generate relative movement with the housing 11 to close the first opening 21. ... Figure 2 The cigarette holder 10 and the housing 11 generate relative movement in the circumferential direction to open or close the first opening 21. However, the relative movement of the cigarette holder 10 and the housing 11 of the present invention is not limited thereto. In other embodiments, the cigarette holder 10 and the housing 11 generate relative movement in the circumferential direction to open or close the first opening 21.

[0045] Preferably, the air intake area of ​​the first airflow path is not less than 50% of the air intake area of ​​the second airflow path. This is advantageous in that when the aerosol generating device 1 has the first airflow path, the air pressure sensor will not feel the pressure and will not be triggered; when the aerosol generating device 1 has the second airflow path, the air pressure needs to flow from the bottom to the atomizing part 30 so that the pressure sensor can feel the air pressure, that is, the air pressure sensor can feel the suction pressure and trigger the circuit to be turned on.

[0046] Continue to refer Figure 1 and Figure 2, the aerosol generating device 1 of the present invention further includes a second opening 22, which is provided in the housing 11, and the second airflow path includes the outside air flowing into the atomizing chamber 31 from the second opening 22. That is, the mouthpiece 10 and the housing 11 generate relative movement to open the first opening 21, and when the user inhales through the product inhalation port 13, the outside air can flow into the aerosol channel through the first opening 21 and then flow out from the product inhalation port 13, forming a first airflow path. The outside air will not flow into the aerosol channel through the second opening 22. The mouthpiece 10 and the housing 11 generate relative movement to close the first opening 21, and when the user inhales through the product inhalation port 13, the outside air can flow into the aerosol chamber 31 through the second opening 22, and then flow into the aerosol channel from the atomizing chamber 31, and then flow out from the product inhalation port 13, forming a second airflow path. The outside air will not flow into the aerosol channel through the first opening 21.

[0047] That is, when the first opening 21 is in an open state, the user inhales through the product inhalation port 13, the outside air will not flow into the aerosol channel through the second opening 22, no airflow passes through the atomization chamber 31, and the air pressure sensor will not be triggered; when the first opening 21 is in a closed state, the user inhales through the product inhalation port 13, the outside air will not flow into the aerosol channel through the first opening 21, but flow into the atomization chamber 31 through the second opening 22, the air pressure sensor is triggered, the aerosol generated is mixed with the fresh air flowing into the atomization chamber 31, and then flows into the aerosol channel from the atomization chamber 31 for the user to inhale through the product inhalation port 13.

[0048] Preferably, in the direction from the cigarette holder 10 to the housing 11 ( Figure 1 The first opening 21 is closer to the inhalation port 13 than the second opening 22. This is beneficial in that when the aerosol generating device 1 has a first airflow path, the outside air will not flow into the atomization chamber 31 through the second opening 22, but will flow into the atomization channel through the first opening 21, so that the air pressure sensor will not feel the pressure and will not be triggered.

[0049] It should be noted that the number, specific position and size of the first openings 21 are not limited, and can satisfy the requirement that the aerosol generating device 1 has a first airflow path and a second airflow path. Figure 7 The cigarette holder 10 of the present invention has an insertion end 14, and the insertion end 14 is movably disposed at one end of the first inner cavity 11a, and the first opening 21 is disposed at the insertion end 14. Figure 7 As shown in FIG. 1 , two first openings 21 are provided on the insertion end 14. When the insertion end 14 of the cigarette holder 10 is moved in a direction toward the housing 11 ( Figure 1 After being inserted into the first inner cavity 11a of the housing 11 (as shown in the direction A in FIG. 1 ), Figure 2 , the first opening 21 on the cigarette holder 10 is shielded, so that the first opening 21 is in a closed state; when the insertion end 14 of the cigarette holder 10 is moved away from the housing 11 ( Figure 2 After relative movement occurs between the first inner cavity 11a of the housing 11 and the first inner cavity 11a of the housing 11, Figure 1 , the first opening 21 on the cigarette holder 10 is exposed, so that the first opening 21 is in an open state. Preferably, when the insertion end 14 of the cigarette holder 10 moves relative to the first inner cavity 11a of the outer shell 11 in a direction away from the outer shell 11, the first opening 21 on the cigarette holder 10 is shielded, so that the first opening 21 is in a closed state. When the insertion end 14 of the cigarette holder 10 moves relative to the first inner cavity 11a of the outer shell 11 in a direction toward the outer shell 11, the first opening 21 on the cigarette holder 10 is exposed, so that the first opening 21 is in an open state.

[0050] However, the arrangement of the first opening 21 is not limited thereto, and the first opening 21 is opened or closed when the cigarette holder 10 and the housing 11 move relative to each other, so as to form a first airflow path or a second airflow path. In other embodiments, the first opening 21 is arranged on the housing 11, and when the cigarette holder 10 and the housing 11 move relative to each other, the first opening 21 is opened or closed.

[0051] Continue to refer Figure 3 , the cigarette holder 10 of the present invention is elastically supported on the shell 11 by the first elastic member 40. During the process in which the cigarette holder 10 and the shell 11 generate relative movement to open or close the first opening 21, the first elastic member 40 is compressed or stretched. In this embodiment, the cigarette holder 10 generates relative movement with the shell 11 in the direction toward the shell 11, and the first elastic member 40 is compressed; the cigarette holder 10 generates relative movement with the shell 11 in the direction away from the shell 11, and the first elastic member 40 is stretched and reset. Preferably, refer to Figure 1 , the aerosol generating device 1 is in the initial state, the first elastic member 40 is in the original state and is not compressed, under the elastic force of the first elastic member 40, the mouthpiece 10 is elastically supported on the shell 11, and the first opening 21 is in the open state; when the user needs to inhale the aerosol generating system, the mouthpiece 10 is controlled to move relative to the shell 11 in the direction toward the shell 11, that is, the mouthpiece 10 is pressed, and at this time, the first elastic member 40 is compressed. After the inhalation is completed, the mouthpiece 10 is controlled to move relative to the shell 11 in the direction away from the shell 11, and the first elastic member 40 is reset.

[0052] In addition, reference Figure 2 and Figure 5, the cigarette holder 10 of the present invention can move in a direction toward the housing 11 until it abuts against one end of the housing 11 to close the first opening 21, and the first elastic member 40 is compressed; Figure 1 and Figure 3 The cigarette holder 10 can move in a direction away from the housing 11 to be separated from the one end of the housing 11 to open the first opening 21, and the first elastic member 40 is reset.

[0053] In addition, one of the ends of the cigarette holder 10 located in the first inner cavity 11a and the inner wall of the first inner cavity 11a is provided with a convex portion, and the other is provided with a concave portion, and the concave portion cooperates with the convex portion to limit the terminal position of the cigarette holder 10 moving in a direction away from the housing 11. In this embodiment, reference Figure 3 , a convex portion 15 is provided at one end of the cigarette holder 10 located in the first inner cavity 11a, and a concave portion 23 is provided on the inner wall of the first inner cavity 11a, and the concave portion 23 cooperates with the convex portion 15. After the cigarette holder 10 moves a certain distance in the direction away from the shell 11, the concave portion 23 and the convex portion 15 abut against each other in the moving direction of the cigarette holder 10, thereby limiting the further movement of the cigarette holder 10. That is, the presence of the concave portion 23 and the convex portion 15 not only enables the cigarette holder 10 to be elastically supported in the shell 11, but also limits the further movement of the cigarette holder 10 when the cigarette holder 10 moves to the terminal position relative to the shell 11, thereby preventing the cigarette holder 10 from slipping out of the first inner cavity 11a of the shell 11.

[0054] refer to Figure 3 The aerosol generating device 1 of the present invention further includes: a liquid storage part 20, in which smoke liquid is stored, and the liquid storage part 20 has a liquid outlet 24. When the mouthpiece 10 and the shell 11 generate relative movement to open the first opening 21, the liquid outlet 24 is closed, and when the mouthpiece 10 and the shell 11 generate relative movement to close the first opening 21, the liquid outlet 24 is opened. That is, when the aerosol generating device 1 is not in use, the smoke liquid will not flow into the atomization part 30, and when it is in use, the smoke liquid flows into the atomization part 30 to prevent leakage. Therefore, the aerosol generating device 1 of the present invention controls the outflow of smoke liquid in the liquid storage part 20 through the relative movement of the shell 11 and the mouthpiece 10.

[0055] Preferably, during the relative movement between the cigarette holder 10 and the housing 11 to open or close the first opening 21, the liquid storage part 20 moves synchronously with the cigarette holder 10. The connection method between the cigarette holder 10 and the liquid storage part 20 is not limited, as long as the synchronous movement can be achieved. Preferably, the cigarette holder 10 and the liquid storage part 20 are connected by a hook and move synchronously when pushed. Further preferably, the cigarette holder 10 is threadedly connected to the liquid storage part 20. Further preferably, the cigarette holder 10 and the liquid storage part 20 are connected by bolts.

[0056] refer to Figure 3 and Figure 8 The aerosol generating device 1 of the present invention further comprises: a valve body 26, which is inserted into the liquid outlet 24 and moves along the movement direction of the mouthpiece 10 ( Figure 8 The liquid outlet 24 has a first blocking portion 27 and a second blocking portion 28 arranged at intervals, and the second blocking portion 28 is closer to the atomization portion 30 than the first blocking portion 27; a second elastic member 25 is arranged in the liquid outlet 24, one end of which is connected to the first blocking portion 27, and the other end is connected to the valve body 26. In this embodiment, the valve body 26 can move in a direction toward the first blocking portion 27 to open the liquid outlet 24, and the second elastic member 25 is compressed; or, the valve body 26 can move in a direction away from the first blocking portion 27 until it abuts against the second blocking portion 28 to close the liquid outlet 24, and the second elastic member 25 is reset. Preferably, the valve body 26 moves in a direction toward the first blocking portion 27 to open the distance of the liquid outlet 24 ( Figure 4 Preferably, before the valve body 26 moves toward the first blocking portion 27 to open the liquid outlet 24, the valve body 26 moves at least 0.5 mm. This helps prevent the heating element 32 in the atomizing chamber 31 from burning dry.

[0057] In other words, the mouthpiece 10 of the present invention can move in the direction toward the shell 11 until it abuts against one end of the shell 11 to close the first opening 21, and the first elastic member 40 is compressed; at the same time, the valve body 26 can move in the direction toward the first blocking portion 27 to open the liquid outlet 24, the second elastic member 25 is compressed, the liquid outlet 24 of the liquid storage portion 20 is opened, and the smoke liquid can flow out to the heating element 32 or the oil guide buffer body in the atomization portion 30; the air pressure sensor can sense the suction pressure and trigger the circuit to be connected.

[0058] Alternatively, the mouthpiece 10 can move in a direction away from the shell 11 until it is separated from the one end of the shell 11 to open the first opening 21, and the first elastic member 40 is reset; at the same time, the valve body 26 can move in a direction away from the first blocking portion 27 until it abuts against the second blocking portion 28 to close the liquid outlet 24, the second elastic member 25 is reset, and the liquid outlet 24 of the liquid storage portion 20 is closed; the pressure is not transmitted to the air pressure sensor, and the air pressure sensor is shielded to avoid starting the heating element 32 and causing dry burning.

[0059] In this embodiment, along the movement direction of the cigarette holder 10, one end of the liquid storage part 20 is fixedly connected to the cigarette holder 10, and the other end is inserted into the atomization part 30. Preferably, the other end of the liquid storage part 20 is inserted into the extension part 33 of the atomization part 30. One end of the first elastic member 40 is connected to the atomization part 30, and the other end is connected to the other end of the liquid storage part 20. Thus, the cigarette holder 10 can move in the direction toward the housing 11 until it abuts against one end of the housing 11, the first elastic member 40 is compressed, the second elastic member 25 is compressed, the cigarette holder 10 can move in the direction away from the housing 11 until it is separated from the one end of the housing 11, the first elastic member 40 is reset, and the second elastic member 25 is reset.

[0060] During the movement of the mouthpiece 10, at least when the mouthpiece 10 abuts against one end of the housing 11, the valve body 26 abuts against the atomizing part 30. Preferably, before the mouthpiece 10 moves in the direction toward the housing 11 and abuts against one end of the housing 11, the first elastic member 40 is compressed, and the valve body 26 abuts against the atomizing part 30; as the mouthpiece 10 continues to move in the direction toward the housing 11, the second elastic member 25 is compressed, and the liquid outlet 24 of the liquid storage part 20 opens until the mouthpiece 10 abuts against one end of the housing 11. More preferably, before the mouthpiece 10 moves in a direction toward the shell 11 until it abuts against one end of the shell 11, the first elastic member 40 is compressed, the valve body 26 does not abut against the atomization part 30, the second elastic member 25 is not compressed, and the liquid outlet 24 of the liquid storage part 20 is closed; when the mouthpiece 10 abuts against one end of the shell 11, the valve body 26 abuts against the atomization part 30, at which time the second elastic member 25 is compressed and the liquid outlet 24 of the liquid storage part 20 is opened.

When the liquid storage part 20 is in use, the first opening 21 is closed, the combination of the mouthpiece 10 and the liquid storage part 20 is in a state close to the heating element 32 of the atomizing part 30, the liquid outlet 24 of the liquid storage part 20 is open, and the smoke liquid can flow out to the heating element 32 or the oil guide buffer body in the atomizing part 30.

[0066] In addition, preferably, the liquid storage part 20 uses food-grade materials, such as PC, PLA, PEEK and other materials. The valve body 26 is made of high temperature resistant and stable materials, such as metal, PEEK, ceramic and other materials. The heating element 32 is preferably a ceramic atomization core, which is made of porous ceramic material and has a certain oil storage capacity. A heating wire or a printed circuit is embedded inside, and the heating wire is close to the bottom surface of the ceramic body. Preferably, the heating wire can be made of metal materials such as nickel-cadmium alloy, nickel, stainless steel, etc., or it can be a breathable heating coating. Preferably, the outer layer of the heating element is fixed with a silicone jacket, which can also play a role in heat insulation. Preferably, the aerosol channel airway surrounds the liquid storage part 20.
